At the end of our list of synonyms of the typical form of this Antelope it will be observed that we have added, with a mark of doubt, _Tragelaphus gratus_ of Rochebrune’s ‘Faune de la Sénégambie,’ upon which Dr. Trouessart has based his _Tragelaphus obscurus_. All that can be said of Rochebrune’s figure is that, if correctly drawn, it cannot have been taken from _Limnotragus gratus_, which is at once recognizable by its elongated hoofs, and that it is _more likely_ to have been based on an example of the present species. But we have already on more than one occasion alluded to the untrustworthiness of Dr. Rochebrune’s work, and think it hardly worth while to discuss the subject further. The Harnessed Antelope is frequently brought alive to Europe from the ports on the West Coast of Africa and does nicely in captivity. It was well represented in the great Knowsley Menagerie, where it frequently bred. In May 1845, as we learn from the ‘Gleanings,’ there was at Knowsley a herd of two males and four females, of which three were then expected to produce young. Both sexes were figured by Waterhouse Hawkins on the 28th plate of that work. Several specimens of it were sold at the dispersal of the Knowsley Menagerie in 1851. The Zoological Society of London has exhibited specimens of this handsome Antelope ever since its gardens were instituted, but it does not appear to have bred there. Dr. Percy Rendall, F.Z.S., brought home a fine male from the Gambia in 1890, and in the following year a pair was presented to the Society by Sir R. B. Llewelyn, K.C.M.G., the Governor of that Colony. In Mr. Smit’s illustration of this species (Plate LXXXIX.) the figures of the male and female were taken from the Zoological Society’s specimens; the young one in the front was drawn from a specimen from Fantee, in the British Museum. _November,_ 1899.
